Heavy ion collisions at SIS 18 energies produce nuclear matter at similar temperature and density as present in neutron star mergers. The aim of this work is to constraint the equation of state of dense nuclear matter from collective flow observables. The azimuthal anisotropy is known to be very sensitive to the employed equation of state and is characterized by flow coefficients. For the calculation of flow coefficients a hadronic transport model (SMASH) is employed, where the equation of state enters the calculation in form of nuclear mean field potentials. A Skyrme potential is used with different parameter sets to vary the stiffness of the equation of state. This is a first step towards a more systematic study with a state-of-the-art description of nuclear potentials and Bayesian parameter estimation.
